Smoke from wildfires has been a fact of life for virtually everyone. Even here in Michigan, we have seen smoke from the fires on the West Coast. At times, it has been dense enough that some folks with respiratory illnesses have had to stay inside and use air purifiers to breathe. Researchers at Colorado State University have found that even trees are affected by smoke, but they have a system designed into them to avoid damage that smoke can cause.
Plants have pores called stomata on their leaves, which do the opposite of our lungs by taking in carbon dioxide and expelling oxygen. However, taking in smoke could interfere with this process. The researchers found that when smoke wafted across ponderosa pines, the trees responded by closing their stomata, essentially holding their breath.
Smoke in the air is not a new feature in the natural world. Fires are expected whenever there are forests and dry weather, even without human carelessness. Since trees are affected by smoke, they have a designed response to what might damage their ability to take in carbon dioxide. This is just one more example of the incredible thought and planning that went into the creation.
Genesis 1:11-12 tells us that God created the fruit tree, but as we look deeper into the makeup of trees, we see the handiwork of God displayed in this remarkable design. Research is ongoing to see if this is true of all plants, including those we depend on for food. This question becomes very important with the increase in wildfires in the past two years.
